Defence lawyer Barry Roux is seen before an appeal by state prosecutors against South African paralympian Oscar Pistorius's conviction last year at the Supreme Court of Appeal (SCA) in Bloemfontein, November 3, 2015. Pistorius, freed on parole last month after serving a fifth of his prison term for killing his girlfriend, faces years more in jail if state lawyers can get his conviction scaled up to murder from culpable homicide. Prosecutors will argue before the Supreme Court that a high court judge was wrong to let Pistorius off the more serious charge after he fired four shots through a door on Valentine's Day 2013, killing Reeva Steenkamp.
